Study Notes
Natural Selection
- Underpopulation is not a step in natural selection.
- Natural selection involves variation, struggle for existence, and survival of the fittest.
- Fitness is environment-specific and species-specific, measured across several generations.
- Higher reproductive rate contributes to higher fitness.
Ecology
- Ecology is the scientific study of interactions among living organisms and their environment.
- The word "ecology" comes from the Greek words oikos (household) and logos (study).
Theophrastus
- Theophrastus is considered the father of botany.
- He wrote the book "Enquiry into plants".
Biogeography
- Humboldt is considered the father of biogeography.
Hierarchical Systems
- Hierarchical systems in ecology are stable.
- Hierarchies emerge because they are efficient.
- Hutchinson proposed a hierarchical system in ecology.
- Hierarchy levels include organelles, cells, tissues, organs, organisms, populations, communities, ecosystems, and biomes.
Biodiversity
- Biodiversity is the variety of life on Earth.
- Alpha (α) biodiversity refers to diversity within an ecosystem.
- Beta (β) biodiversity refers to diversity between ecosystems.
- Gamma (γ) biodiversity refers to diversity among geographic regions.
Species
- A species is defined as a group of organisms that can interbreed and produce viable offspring.
- There is more biodiversity in areas with less competition and more predation.
